All language subtitles for 20 - External Editing Continued

Now that we have a better understanding

of many of the key terms
associated with Lightroom,

we can return to our preferences panel
and continue our discussion

on external editing.

So remember that

external editing
allows us to take an image and edit it in

an external application.

And the first option here is Adobe
Photoshop.

CC in the file format menu.

We can choose which file format
we want this image exported in,

and normally it's a good idea to have TIFF
selected.

Next is the color space.

We can either use pro photo rg B

adobe rg B display P three or s rgv.

We now know that pro photo RG B
is the largest

color space with the widest color range.

For this reason,
exporting images in this format.

It's 16 bit color depth will preserve
the highest level

of tone detail,
so I'll leave it as pro photo.

RGV The bit depth really depends

if you're going to be working with JPEG
files, you can leave it as eight bit.

If you're going to be exporting raw
files or DNG files,

you'll want to change that to 16.

The next thing we can specify
here is the resolution.

This is another important

concept to understand
when it comes to photography.

Resolution refers to the pixel density
in every square inch of your image.

The higher the pixel density, the better
the quality.

To better understand
this concept, take a look

at these two identical images
in this illustration.

The image on the left has a pixel

density of 72 dots per inch.

The picture on the right
has a resolution of 300 dots per inch.

We can clearly see that the 300

DPI is a better overall quality shot.

The image is sharper
and has a smoother transition of colors.

It's best to set the resolution

between 240 to 300.

This will ensure that the image retains
optimal quality

regardless of what
you intend to use it for.

To obtain good quality prints,

you require a print resolution
of at least 300 dots per inch for images

destined for a web gallery,
or only to be viewed through a monitor.

A resolution of 72 to 150 is efficient.

We'll leave the default setting
because we can always

reduce the resolution of an image later
on without losing quality.

Keep in mind that the same is not true.

If you try to increase
the resolution of an image,

this will lead to quality loss
and a distorted image.

The next setting we have here
is compression.

Compression refers
to reducing the overall size of an image.

So its file size is smaller.

This translates into preserving more disk
space, which is its biggest advantage.

The two types of compression
methods here are zip and LZ, UW.

Both of them are lossless compression
methods.

That means that no data is being lost
in the compression,

unlike JPEG compression,
the only disadvantage

is that compressed
images require more processing time

to open and close
in your editing application.

Although with high performance processor
in modern computing systems,

this issue is negligible.

You can leave the compression as
the second option group under the heading.

Additional external editor
allows you to specify

a secondary external application
that you can use for editing.

For example, if

you don't use Adobe Photoshop CC
or perhaps you use a different version,

you can select it by clicking choose

and then picking

the application
that you'd like to use on your computer.

So I'll go ahead and select Adobe
Photoshop CS6

because I use that more often than CC.

If you don't have a secondary application
that you'd like to use,

you can ignore these settings altogether.

And the additional menus here are the same
as what we just covered up here.

Stack with original.

We've mentioned
before that image adjustments performed in

Lightroom are nondestructive,
but this means any time

we make a new adjustment to an image,
a new image is automatically created

by placing a checkmark in
stack with original.

This option will ensure that all
images are stacked together.

This will make
more sense when we perform adjustments

on our sample images,
so don't worry about it for now.

Edit externally file naming.

This last setting here gives us the option
to configure

the file names of images
which are exported for editing.

You can see in the sample file

name that a dash in the word edit
are attached to the end of the file name.

So earlier
when we open an image in Photoshop

and we saved it as a tiff file,
you'll notice that Photoshop

automatically added
the edit extension to our file name.

And that's where this comes from.

There are many other options
available in this pull down menu.

If you click on edit
at the very bottom of this menu,

there are a number of customized settings
you can apply right now.

You can see in this text area
we have the file name

a dash in the word edit,
and that's what you saw in the preview.

Since most

of the settings here
are fairly easy to understand.

I'll exit this panel and leave the default
setting

if we wanted to add the date, for example,
I could click insert

and now the date would be added
as part of the file name.

And you can see the example
2005 has been added.

I'll go ahead and delete that
because we don't want to include the date.

So hit cancel
because we've made no changes.
